General Motors is developing a new type of vehicle-to-vehicle communication, dubbed as the V2V, which can be implemented either from in-car hardware or from an app installed on a driver’s smartphone. This way, the vehicles share information on traffic or road hazards. These two methods use Dedicated Short Range Communications, a type of wireless networking.
Travel speeds can be communicated through these devices. This means that when a vehicle at the front communicates that it is stuck in traffic, other drivers can adjust the speeds and routes to avoid the same problem.
The transmitted information could transfer from car to car and will vary depending on what carmakers want to transmit to other vehicles. For example, a vehicle that uses traction control or ESP could notify other vehicles of potentially slippery conditions ahead. V2V could also permit drivers to adjust speeds to avoid getting stuck at red lights.
GM will be displaying the technology in Orlando this week but it will take a long time before it could be viable. The devices become more accurate when there are more cars that have them on the road. This is because the technology depends on a mesh network. GM expects that the system will already be in use by the end of the decade.
But even so, tying the system to a smartphone app theoretically permits the network to broaden quicker than if V2V is only used by a few new vehicles. The National Highway Traffic Safety Administration supports this technology, saying that it will prevent several types of crashes, particularly those that take place within intersections. The NHTSA believes that it may lead to the avoidance of about 81% of accidents.
